Question about JVC RX-778V

1 Answer

No Prologic Surround Sound

I own a JVC RX-778V home theater audio/video control receiver.

The unit has worked perfectly for years.

Last night, I popped in a DVD and got -- ugh, no sound.

Debugging activities took most of the afternoon today -- replaced
digital audio cable, confirmed DVD player works on analog connected
directly to the TV, etc.

Current symptoms:

o get sound out of only one speaker now in ALL modes.
o no sound whatsoever when Dolby / Prologic / Surround Sounds is on.
o get DVD audio over analog outputs only (out of one speaker only).

I'm 99% certain that menu configurations are correct.

Has anyone ever encountered such a failure?

What's more likely, digital audio out from DVD player is shot, or
surround sound in receiver is shot?

Not sure how to proceed. Again, I've read the manual word for word,
experimented with zillions of configs.

Any advice greatly appreciated.

Re: No Prologic Surround Sound

Im thinking the reciever is set to get its audio from somehwere other than the dvd, sounds like you did most of the troubleshooting but do you get audio out of the reciever if its just playing the radio or something other than a dvd?

I would like to use my jvc home theater while watching tv. But i have no idea how or what wires to use to make this work.

You will need a 2RCA to 2RCA audio cable as shown below. Connect the audio out socket of your TV to the Aux or TV/SAT input of the JVC. When you want to hear the TV sound through the JVC system just select the appropriate input on the JVC. If you want the surround speakers to work, select ProLogic or All channel stereo on the JVC's surround settings.Because by default the radio or TV sound is only stereo, so only the front left and right speakers will work. PLII will convert 2 channel to 5.1.

Subwoofer not working.... JVC surround sound system 778V Subwoofer Part Number SP-PW37-SUB I hear a hum coming from unit so there's power going to it. I hear weak bass thumps with volume turned all the way...

A connectivity check could provide the solution, notice any wrong wire connections on device or any other devices requiring interconnection. The woofer would perform properly when the connections that provide current for woofing are approapiate

important notes
1. Trace the connection from Recorder or sound output to the woofer device
2. The wiring connections should be sound and video ouput into sound and video output into woofer.
3. The connections if any problems would be located at the stereo recorder or device producing the spund and video. Check the connections of wires on the recorder device ensuring rewiriing
4. finally, adjust the equalisers if any the buttoms could have been disbled by master switch hindering full blaster boost sound.

I have my jvc rx-778v that always overloads. why is that?

There could be a couple of reasons that its overloading one is make sure that there is no bare wire touching at all.The other thing it could be is the ohms rating over your speakers may be to low for you receiver.Most receiver can handle 8 ohms to 6 ohms there are a few that can handle 4 ohms check your speaker ohms rating then check how low your receiver can handle with out going into overload.

How much is a JVC RX 750v worth?

I have this same unit. It is many years old, and does not handle any modern codecs, nor home theater duties. It was, however, a very good unit for its day. If I were to sell mine, I would not accept less than 100 US with remote.

Center Channel Audio

There are probably several sound settings on the receiver :
Dolby surround , stereo, theater, SACD etc.
Try another setting other than the one you have
